Right,this morning I completed the dastardly deed!
For the past few weeks I have been lifting the bonnet and peering into the depths,only to close the bonnet again because it looked just too complicated.
But,this morning I got the car over the pit and decided to take the steel sump guard off and see if it looked any simpler from below which,to be honest,it didn't.
Eventually I managed to find where the horn is situated (with the aid of an inspection mirror on a telescopic handle) and found that with a bit of dexterity I could just undo the horn from where it's fixed.I then removed the horn,complete with bracket,and diconnected the power supply plug.(Don't forget to refit the bolt)
It was then a case of where to mount the new twin tone horns.
Just in front of the wheel arch liner there is what seems to be an unused bracket,probably there for some option or other,but is just large enough to mount the new horns,there's even a couple of holes in the bracket so no drilling was needed.
Next job was to wire them up.Try as I might I couldn't find anything to fit in the end of the plug that was fitted to the original horn,I even tried to trim some male spade terminals to fit into the plug but decided the only thing to do was cut the plug off and use some heat shrink butt terminals to extend the cable to the new horns.
I was in two minds whether to fit a relay,but seeing as the original horn is just one half of a pair of twin tones (just a high tone) I decided not to.It's not as if the horns are being used constantly,you normally give just a quick toot so it shouldn't be a problem.
Obviously if I were fitting air horns that require a compressor,then I would fit a relay.
I also fitted some new convoluted cable protector so the cables wouldn't get wet or damaged.
A quick test 'parp' and all was good,much improved,much louder and a nice twin tone sound.
Then it was just a case of re-fitting the sump guard (copper grease on all bolts) and job done.It took me about an hour and a half.
Ah! yes,the horn is mounted right at the front just above and to the right of the N/S fog lamp.
I was going to take some photos of the job progress but,
A: I forgot
and
B: There wouldn't have been enough room.
